|Route outline (key)|
The original B4100 was a rural B-road in east Warwickshire.
The road started on the A423 on the northern edge of Southam and headed northeastwards across the fields. It crossed the Grand Union Canal at the top of the Stockton Locks and then continued to bypass Leamington Hastings. After going over the M45 the road entered Dunchurch, ending in the centre of town at a crossroads on the A45 (present B4429). The road ahead was the A426 and that road took over the whole of the B4100 in the 1960s.
